- *    Namely: MosaicMigrator.prototype = Object.create(MigratorPrototype);
- * 3. Set classDescription, contractID and classID for your migrator, and set
- *    NSGetFactory appropriately.
- * 4. If the migrator supports multiple profiles, override the sourceProfiles
- *    Here we default for single-profile migrator.
- * 5. Implement getResources(aProfile) (see below).
- * 6. If the migrator supports reading the home page of the source browser,
- *    override |sourceHomePageURL| getter.
- * 7. For startup-only migrators, override |startupOnlyMigrator|.

-   * Returns an array of "migration resources" objects for the given profile,

-   * profiles.
-   *
-   * Each migration resource should provide:
-   * - a |type| getter, retunring any of the migration types (see
-   *   nsIBrowserProfileMigrator).
-   *
-   * - a |migrate| method, taking a single argument, aCallback(bool success),
-   *   for migrating the data for this resource.  It may do its job
-   *   synchronously or asynchronously.  Either way, it must call
-   *   aCallback(bool aSuccess) when it's done.  In the case of an exception
-   *   thrown from |migrate|, it's taken as if aCallback(false) is called.
-   *
-   *   Note: In the case of a simple asynchronous implementation, you may find
-   *   MigrationUtils.wrapMigrateFunction handy for handling aCallback easily.
-   *
-   * For each migration type listed in nsIBrowserProfileMigrator, multiple
-   * migration resources may be provided.  This practice is useful when the
-   * data for a certain migration type is independently stored in few
-   * locations.  For example, the mac version of Safari stores its "reading list"
-   * bookmarks in a separate property list.
-   *
-   * Note that the importation of a particular migration type is reported as
-   * successful if _any_ of its resources succeeded to import (that is, called,
-   * |aCallback(true)|).  However, completion-status for a particular migration
-   * type is reported to the UI only once all of its migrators have called
-   * aCallback.
-   *
-   * @note  The returned array should only include resources from which data
-   *        can be imported.  So, for example, before adding a resource for the
-   *        BOOKMARKS migration type, you should check if you should check that the
-   *        bookmarks file exists.

-   * @param aProfile

-   *        In the case of multiple-profiles migrator, it is guaranteed that
